BackgroundBackground
Stroke, a blockage or bleed
in the brain, represents one
of the leading causes
of morbidity in Canada1
Resultant signs & symptoms can have a negative impact on one’s ability to live their daily life1
Stroke places a large economic burden ($2.8 billion) on the Canadian Health Care System1

Treadmill training energy expenditure & CV demands of gait in individuals with stroke6,7
VO2max of at least 15ml/kg/min for women & 18 ml/kg/min for men is required for independent living8
Individuals with stroke who participated in an aerobic program had an average in VO2max of 13% compared to control3
aerobic fitness has been associated with functional gains including mobility, falls, & ability to carry out ADLs9

Background: Neuroprotective Effect
and Neuroplasticity
Background: Neuroprotective Effect
and Neuroplasticity Aerobic exercise has a neuroprotective effect on
the brain Brain derived neurotrophic factor appears to be
most sensitive to regulation via exercise It may be of importance in mediating the benefits
of exercise on neural plasticity & the benefits of exercise on CNS health
Important post stroke as neuroplasticity is required in order for neural reorganization & regeneration to occur, resulting in function of the individual10

High variability among the participants, particularly stroke severity, likely contributed to lack of significance
The participants in the Pohl29 study had more severe functional deficits (non-ambulatory or required assistance) & it was the only study that had significant findings

Discussion: Participants cont.Discussion: Participants cont.
More severely affected participants likely had lower VO2max due to deconditioning post stroke & thus had more to gain from an aerobic intervention3,4
Therefore, aerobic activity is likely important in ADL function in those with greater functional deficits
Additional research is needed

Heterogeneity of exercise dose is the most prominent issue impacting outcomes
Duration: ACSM: 15-20 wk length intervention may be an
adequate min standard for healthy populations to assess effectiveness of various doses of aerobic exercise11
We suggest that the length of intervention should meet this criteria as this is the most evidence based guideline available

Macko et al28 had the longest study period, however had no significant findings This may be due to the use of the RMI, a dichotomous
scale relating specifically to mobility Because participants were ambulatory at study start,
they may have reached a ceiling effect Pohl et al29 used the same OM, but with initially
non-ambulatory participants Less likely to reach same ceiling effect

Intensity: ACSM: to achieve cardiorespiratory benefits from

Large variability in control group therapy 3 of the control groups participated in walking
however at a lower dose than the experimental group27,28,29

It is likely that a training stimulus may have improved ADLs in those studies that involved conventional PT in the control group
It may be more pertinent to compare aerobic exercise to conventional PT in order to determine if aerobic exercise should be incorporated as part of a conventional PT program

ConclusionConclusion
Adequate dose must be achieved to see changes in ADLs in individuals post stroke
Higher quality & more specific studies are required to determine a dose response relationship for aerobic exercise post stroke & to find patterns among studies
OMs must be specific to the intervention

Clinical ImplicationsClinical Implications
Limited evidence suggests that aerobic exercise has positive effects on ADLs in non-ambulatory individuals post stroke
Aerobic exercise should be used in conjunction with conventional PT as there is limited evidence to support its use in improving ADLs in individuals post stroke
Individuals post stroke must persist with an aerobic exercise program to continue to see changes in ADL function
